Definition

The meninges are a protective lining around the brain and spinal cord. A meningioma is a tumor of these linings. Most meningiomas do not cause symptoms. But, if the meningioma grows, it can push on important parts of the brain. This may lead to symptoms such as vision problems, seizures, weakness, or language problems. These tumors may be grade I, II, or III. Type III is the most aggressive type.

Malignant meningiomas (also called anaplastic or grade III) are less common. These tumors are faster growing. They often cause problems and can cause some swelling in the brain.

Some meningiomas may require some form of therapy, surgery, and/or radiotherapy. The treatment will depend on the location of the tumor.

Treatment

Treatment will depend on the size and location of the tumor, its rate of growth as well as your general health. The main types of treatment for meningiomas are:

Surgery

Surgery may be recommended if the tumor is located in an area that is easily reached. Most surgeries can be done without causing neurologic damage.

Embolization

Tumors need a blood flow to survive. In some instances, prior to surgery, a catheter may be inserted into blood vessels supplying the tumor. It will disrupt the flow of blood to the tumor. This will make the tumor shrink. The smaller tumor can then be removed with surgery.

Radiation Therapy

Some tumors may be located in an area the is difficult or to dangerous to operate on. Radiation may be used on its own if the tumor is causing symptoms and cannot be removed with surgery. The radiation therapy is an effective way of treating the tumor and stopping its growth.

If the tumor is higher grade, radiation is generally considered. In this case, radiation may be given either on its own or after surgery to help prevent the tumor from coming back.

Your radiation oncologist will describe how the therapy is delivered and how many treatments are needed. You may receive 25-40 treatments on a daily basis, or far fewer treatments if you are having stereotactic radiosurgery. This type of surgery delivers higher doses of radiation each treatment.

Chemotherapy

Chemotherapy
is used only if other treatment modalities are no longer adequate. Your oncologist will discuss the options and choice of medications.
